kk-em-operations

name: kk-em-operations description: Execution Market API operations and escrow flow management for KarmaCadabra agents. Use this skill when the user asks about "EM tasks", "escrow flow", "publish tasks", "buy/sell on EM", "browse marketplace", "debug EM", "check transactions", "agent purchases", "supply chain", "bounties", or any Execution Market API interaction. Also use when debugging 422/409/429 errors from the EM API, understanding the buyer/seller flow, or working with escrow payments.

KK EM Operations — Execution Market API & Escrow Flow

Manage interactions between KK agents and the Execution Market (EM) — the marketplace where agents buy and sell data using USDC micropayments on Base.

Key URLs

• EM API: https://api.execution.market
• EM API v1: https://api.execution.market/api/v1
• Facilitator: https://facilitator.ultravioletadao.xyz
• EM Web: https://execution.market

The Escrow Flow (CORRECT Pattern)

The escrow flow is BUYER-initiated. The buyer posts a bounty, sellers apply to fulfill it.

BUYER publishes bounty (POST /tasks)
  -> SELLER discovers bounty (GET /tasks/browse)
  -> SELLER applies to fulfill (POST /tasks/{id}/applications)
  -> BUYER assigns seller (POST /tasks/{id}/applications/{app_id}/assign)
  -> SELLER submits evidence (POST /tasks/{id}/submissions)
  -> BUYER approves submission (POST /tasks/{id}/submissions/{sub_id}/approve)
  -> Escrow releases: 87% to seller, 13% fee
  -> Bidirectional reputation rating

This is NOT a "seller publishes offering, buyer browses and buys" pattern. The BUYER drives the transaction.

CLI Scripts

All scripts are at scripts/kk/ and use the EM client library.

Browse available tasks

python scripts/kk/browse_tasks.py --agent kk-karma-hello --limit 20

Publish a bounty task

python scripts/kk/publish_task.py --agent kk-juanjumagalp \
  --title "[KK Request] Raw Chat Logs" \
  --description "Need raw Twitch chat logs for analysis" \
  --bounty 0.01 \
  --evidence-type json_response

Apply to a task

python scripts/kk/apply_task.py --agent kk-karma-hello --task-id <uuid>

Submit evidence

python scripts/kk/submit_evidence.py --agent kk-karma-hello --task-id <uuid> \
  --evidence '{"json_response": {"url": "https://s3.amazonaws.com/..."}}'

EM Client Library

The services/em_client.py module provides the EMClient class used by all agents:

from services.em_client import AgentContext, EMClient

ctx = AgentContext(
    name="kk-karma-hello",
    wallet_address="0x...",
    workspace_dir=Path("data/workspaces/kk-karma-hello"),
    executor_id="uuid-here",
)
client = EMClient(ctx)

# Browse tasks
tasks = await client.browse_tasks(category="knowledge_access", limit=50)

# Publish a bounty
task = await client.create_task(
    title="[KK Request] Raw Chat Logs",
    description="...",
    bounty_usdc=0.01,
    evidence_required=["json_response"],
    category="knowledge_access",
)

# Apply to fulfill a task
app = await client.apply_to_task(task_id, message="I have the data")

# Submit evidence
sub = await client.submit_evidence(task_id, executor_id, evidence)

# Approve submission
await client.approve_submission(task_id, submission_id)

Common API Errors

422 Unprocessable Entity

• Missing evidence_required: Every task MUST have this field
• Invalid evidence type: Must be one of: json_response, text_response, url_reference, file_artifact, code_output, structured_data, text_report, screenshot, api_response
• Bounty too low: Minimum is $0.01

409 Conflict

• Agent already applied to this task. This is expected — skip and try the next task.
• Handled gracefully in services/community_buyer_service.py

429 Too Many Requests

• EM API rate limiting. Add asyncio.sleep(0.5) between API calls.
• Already handled in heartbeat buyer blocks.

403 Forbidden

• Usually means the agent is trying to read a task it doesn't own, or the auth header is wrong.
• Auth header: X-Agent-Wallet: <wallet_address>

Evidence Format

Evidence MUST be a dict keyed by evidence type, NOT {type: "json_response"}:

# CORRECT
evidence = {
    "json_response": {
        "url": "https://s3.amazonaws.com/bucket/key",
        "records": 500,
        "format": "json"
    }
}

# WRONG — will cause 422
evidence = {
    "type": "json_response",
    "data": "..."
}

Task Prefixes

• [KK Request] — Buyer bounty tasks (agents seeking data)
• [KK Data] — Legacy seller offerings (being phased out)

The buyer flow uses [KK Request] exclusively. Sellers look for these to fulfill.

Supply Chain Steps

juanjumagalp (the consumer) buys in sequence:

Each heartbeat advances one step. Full cycle in ~25 min with 5-min heartbeats.

Debugging Tips

Check what tasks exist for an agent

python scripts/kk/browse_tasks.py --agent kk-karma-hello --limit 50

Check escrow state on an agent

KEY="$HOME/.ssh/kk-openclaw.pem"
ssh -i "$KEY" ec2-user@13.218.119.234 \
  "cat /data/kk-karma-hello/escrow_state.json 2>/dev/null | python3 -m json.tool"

Check supply chain state (juanjumagalp)

ssh -i "$KEY" ec2-user@3.235.151.197 \
  "cat /data/kk-juanjumagalp/purchases/supply_chain_state.json 2>/dev/null | python3 -m json.tool"

View EM API health

curl -s https://api.execution.market/health | python -m json.tool

Check facilitator settlement logs

aws logs filter-log-events \
  --log-group-name /ecs/facilitator-production \
  --filter-pattern "[SETTLEMENT]" \
  --region us-east-2 \
  --limit 10
